“…In this research, we found that the sprint training protocol used had a positive effect on increasing agility for the players. Our research supports previous research, which concluded that 6-10 weeks of speed training had a positive effect on the performance of young athletes in various sports, such as taekwondo, Pencak silat, and football (Hidayat, 2018;Mathisen, 2016;Mathisen & Pettersen, 2018;Singh & Sathe, 2017).
